UsesSodium Phosphate Dibasic Dodecahydrate is used in method for preparing self-supporting membrane.

General DescriptionSodium phosphate is a colorless crystalline sodium salt. It is widely used as a buffer in molecular biology, biochemistry, and chromatographic studies. It exists in three forms: monobasic (NaH2PO4), dibasic (Na2HPO4), and tribasic (Na3PO4). Monobasic and dibasic forms in varying ratios are commonly used to compose the neutral sodium phosphate buffer solution.
